Compatibility Notes
- Extra power variable-rate (20LB) — recommended for full-power and +P .45 ACP ammunition; variable rate provides progressive resistance through the stroke
- May cause reliability issues with very light target or reduced power loads
- Direct drop-in replacement for recoil spring — no fitting required; firing pin spring requires slide disassembly
Installation
Field-strip the pistol per the owner’s manual to replace the recoil spring. Firing pin spring replacement requires slide disassembly — installation by a qualified gunsmith is recommended for that step. Function test with your intended ammunition before carry or duty use.
